She was right: school was lonely. The eighteen and nineteen year olds didn't socialize with the younger kids, and though there were plenty of students my age and younger [...] their lives were so cloistered and their concerns so foolish and foreign-seeming that it was as if they spoke some lost middle-school tongue I'd forgotten. They lived at home with their parents; they worried about things like grade curves and Italian Abroad and summer internships at the UN; they freaked out if you lit a cigarette in front of them; they were earnest, well-meaning, undamaged, clueless. For all I had in common with any of them, I might as well have tried to go down and hang out with the eight year olds at PS 41.
